I don’t add anything—I suppose I should say that I don’t have THE MECHANIC add anything lol. As for gas, I’m not loyal to any one brand/station but I use only premium. Oil change every 3k, constantly cleaning/washing it, aaaaand I don’t know what else to add....

Just be careful not to start it to often

Wow! What a great notion! I like the way you think...

The additives do not really up the points in your fuel as some would think. If you car is tuned for 91/93 use that fuel. If doesn't state either, then usually 85/87 is the go to, depending on your area. I've had stock beaters all the way to my current build, that should be making north of 1500rwhp. Shell, Chevron, Exxon are my go tos when it comes to gas, unless I need higher octane. Then i'll find whoever has E85. So, back to your question, don't mess with the additives. Either get higher octane fuel to begin with (wont do anything if youre not tuned for it) or leave it alone.

Hope that helps some.

What does the higher octane fuel do? I always get the regular cause my car is old lol.

In a nutshell, higher octane is used when higher compression or temperatures are used in an engine. It reduces the chances of premature or additional ignition, which you've probably heard of as pinging. If when you use regular and you hear pinging, you need to move to a higher octane.

In the case of my Mazda, it's designed to run on regular, but because it has a 13:1 compression ratio, I will actually see a power gain, and possible better fuel efficiency, from going to premium as the gas will ignite more efficiently and with more power.

I should note that not all cars will see a gain in power by switching to premium. Some cars, like Nissan's, recommend it for better fuel economy.

After a battery replacement, what's the minimum distance to drive to be sure my car's catalytic converter passes a CA smog check?

[Wrigley2172]

The only "additive" ive ever used is seafoam. But i put it through the intake rather than adding it to the fuel. My goodness the smoke cloud i got was marvelous im surprised no one called the fire department haha. So long carbon build up!

Hey bro, I'm not even sure what a catalytic converter is lol. But, I would say check the owners manual that's the best bet, or download this software that I have it's called automotive wolf and also I use Carfax app too. But, you could also use Google lol.
